The mobile telephone connection has a digital cordless system with a mechanism (E1) allowing the use of a mobile phone in a first standard in a private telecommunications network and using a second standard, allowing connection to a private exchange. The radio transmitter-receiver (BTS) functions to the second cordless standard (DE) using an interface (C) which finds the position of the private network with respect to the mobile units and converts the signalling protocol from the first mobile telephone standard to the digital cordless standard.

Description

L'invention concerne un dispositif permettant d'utiliser des radiotéléphones GSM dans un réseau radiotéléphonique DECT. Un réseau radiotéléphonique DECT est utilisé classiquement pour permettre aux employés d'une entreprise d'utiliser les services d'un commutateur privé, tout en bénéficiant d'une certaine mobilité sur le site de cette entreprise. Un tel réseau comporte un commutateur privé, des stations d'émission-réception appelées station de base DECT, des terminaux radiotéléphoniques mobiles DECT, et éventuellement des terminaux téléphoniques fixes.The invention relates to a device for using GSM radiotelephones in a DECT radiotelephone network. A DECT radiotelephone network is conventionally used to allow the employees of a company to use the services of a private switch, while enjoying a certain mobility on the site of this company. Such a network comprises a private switch, transmission-reception stations called DECT base station, DECT mobile radio terminals, and possibly fixed telephone terminals.

Un tel réseau permet une certaine mobilité des employés à l'intérieur des locaux d'un site de l'entreprise. Mais certains employés sont amenés à se déplacer à l'extérieur de l'entreprise. Pour pouvoir être joints à peu près partout, ils emportent chacun un terminal radiotéléphonique GSM bénéficiant d'un abonnement pour utiliser un réseau GSM public. Ils sont donc censés utiliser au moins deux types de terminal différents selon qu'ils sont ou non dans un site de l'entreprise.Such a network allows a certain mobility of the employees inside the premises of a site of the company. But some employees have to move outside the company. To be able to be joined almost everywhere, they each carry a GSM radiotelephone terminal with a subscription to use a public GSM network. They are therefore supposed to use at least two different types of terminal depending on whether they are in a company site or not.

La multiplication des terminaux pour un même employé n'est pas pratique, notamment à cause de la multiplication des numéros d'appel. En outre, les employés sont tentés d'utiliser uniquement leur terminal GSM bien que le coût des communications soit plus cher que celui des communications via le réseau privé DECT, et bien que le réseau GSM public ne fournisse pas tous les services qu'on peut obtenir du commutateur privé d'une entreprise. D'autre part, les usagers extérieurs à une entreprise sont tentés d'appeler les employés de cette entreprise via leurs terminaux GSM, et non via les terminaux fixes ou DECT, pour maximiser les chances de les joindre. Il est donc souhaitable que les employés d'une entreprise puissent utiliser leurs terminaux GSM via le réseau privé de l'entreprise.The proliferation of terminals for the same employee is not practical, especially because of the proliferation of numbers. In addition, employees are tempted to use only their GSM terminal, although the cost of communications is higher than that of communications via the DECT private network, and although the public GSM network does not provide all the services it can get private switch from a company. On the other hand, users outside a company are tempted to call the employees of this company via their GSM terminals, and not via fixed terminals or DECT, to maximize the chances of joining them. It is therefore desirable that employees of a company can use their GSM terminals via the company's private network.

Un réseau radiotéléphonique GSM permettant d'utiliser de terminaux DECT dans le réseau est connu de WO 97112488-A (SIEMENS AKTIENGESELLSCHAFT et al. ) et est publié à 3 Avril 1997.A GSM radiotelephone network for using DECT terminals in the network is known to WO 97112488-A (SIEMENS AKTIENGESELLSCHAFT et al. ) and is published April 3, 1997.

Le but de l'invention est de permettre aux employés d'une entreprise d'utiliser leurs terminaux GSM dans une entreprise au même coût et avec les mêmes services que s'il s'agissait de terminaux DECT ; et de permettre à des visiteurs extérieurs, dûment autorisés, à utiliser leurs terminaux GSM comme des terminaux DECT de l'entreprise, pour accéder au réseau public fixe via le commutateur privé de l'entreprise, ou pour être appelés via le réseau public fixe.The object of the invention is to allow the employees of a company to use their GSM terminals in a company at the same cost and with the same services as if they were DECT terminals; and allow outside visitors, duly authorized, to use their GSM terminals as DECT terminals of the company, to access the fixed public network via the private switch of the company, or to be called via the fixed public network.

L'invention sera mieux comprise et d'autres caractéristiques apparaîtront à l'aide de la description ci-dessous et des figures l'accompagnant :

  • La figure 1 représente le schéma synoptique d'un exemple de réseau privé DECT comportant deux exemples de réalisation du dispositif selon l'invention.
  • La figure 2 représente le schéma synoptique d'un exemple de réalisation du dispositif selon l'invention.
The invention will be better understood and other characteristics will appear with the aid of the description below and accompanying figures:
  • FIG. 1 represents the block diagram of an example of a DECT private network comprising two exemplary embodiments of the device according to the invention.
  • FIG. 2 represents the block diagram of an exemplary embodiment of the device according to the invention.

Le réseau privé représenté sur la figure 1 comporte :

  • un commutateur privé PABX,
  • des stations de base de type DECT : DBS1, DBS2, DBS3, reliées au commutateur privé PABX,
  • et deux dispositifs E1 et E2 selon l'invention.
The private network represented in FIG. 1 comprises:
  • a PABX private switch,
  • base stations of DECT type: DBS1, DBS2, DBS3, connected to the private switch PABX,
  • and two devices E1 and E2 according to the invention.

Des terminaux DECT : DT1, DT2, DT3, DT4, communiquent avec les stations de base DECT : DBS1, DBS3, par des liaisons radio conformes à la norme DECT. Le site de l'entreprise considérée est desservi en outre par les dispositifs E1 et E2 selon l'invention, qui permettent d'établir des liaisons radio conformes à la norme GSM, avec des terminaux GSM classiques GT1, GT2, GT3. Le dispositif E1 est relié au réseau privé par une liaison radio conforme à la norme GSM, établie avec une station de base DECT, DBS1 par exemple. Le dispositif E2 est relié au réseau privé par une liaison filaire L. Le commutateur privé PABX est relié notamment à un réseau public fixe PSTN.DECT terminals: DT1, DT2, DT3, DT4 communicate with the DECT base stations: DBS1, DBS3, via radio links to the DECT standard. The site of the company in question is further served by the devices E1 and E2 according to the invention, which make it possible to establish radio links compliant with the GSM standard, with conventional GSM terminals GT1, GT2, GT3. The device E1 is connected to the private network by a radio link conforming to the GSM standard, established with a DECT base station, DBS1 for example. The device E2 is connected to the private network by a wired link L. The private switch PABX is connected in particular to a fixed public network PSTN.

Les terminaux GSM peuvent être utilisés :

  • soit de manière classique, c'est à dire communiquer via un réseau public GSM, en conservant tous les services fournis par ce réseau public GSM;
  • soit choisir le réseau privé, se localiser dans ce réseau, et communiquer avec le réseau privé , et avec le réseau public fixe PSTN via le réseau privé, ce qui leur permet de bénéficier de tous les services de ce réseau prive, notamment : des communications locales avec les autres terminaux fixes ou mobiles du réseau privé, et des communications via le réseau public fixe PSTN. Pour passer par le réseau privé, l'usager d'un terminal GSM doit tout d'abord déclarer son terminal GSM, une fois pour toutes, auprès du réseau privé, en composant un numéro et un code particulier sur son clavier de terminal. Cette procédure de déclaration auprès des dispositifs E1 et E2 permet d'attribuer ce droit d'accès à une liste d'usagers, employés de l'entreprise et certains visiteurs.
GSM terminals can be used:
  • either conventionally, ie communicate via a public GSM network, retaining all the services provided by the GSM public network;
  • choose the private network, locate in this network, and communicate with the private network, and with the fixed public network PSTN via the private network, which allows them to benefit from all the services of this private network, including: communications other fixed or mobile terminals of the private network, and communications via the PSTN fixed public network. To go through the private network, the user of a GSM terminal must first declare his GSM terminal, once and for all, to the private network, by dialing a number and a particular code on his terminal keyboard. This declaration procedure with the devices E1 and E2 makes it possible to attribute this right of access to a list of users, employees of the company and certain visitors.

Chaque dispositif E1 et E2 mémorise, pour chacun des terminaux GSM qui sont considérés comme appartenant au réseau privé, c'est à dire ceux appartenant à l'entreprise et ceux des visiteurs qui ont été dûment déclarés :

  • l'identité internationale d'abonné mobile IMSI (International mobile subscriber identity), et l'identité temporaire correspondante TMSI (Temporary mobile subscriber identity),
  • l'identité DECT appelée IPUI (International Portable User Identity), utilisée dans le commutateur PABX, et le numéro d'annuaire,
  • la relation IMSI/numéro d'annuaire,
  • la relation IPUI/numéro d'annuaire,
  • et optionnellement l'identité de la société propriétaire du terminal.
Each device E1 and E2 stores, for each of the GSM terminals which are considered as belonging to the private network, ie those belonging to the company and those of the visitors who have been duly declared:
  • the international mobile subscriber identity (IMSI) mobile subscriber identity, and the corresponding Temporary Mobile Subscriber Identity (TMSI) temporary identity,
  • the DECT identity called International Portable User Identity (IPUI), used in the PABX switch, and the directory number,
  • the IMSI relationship / directory number,
  • the relation IPUI / directory number,
  • and optionally the identity of the company owning the terminal.

Tout se passe, pour le commutateur PABX, comme s'il traitait des terminaux DECT via une station de base de type DECT, telle que DBS1, DBS2, DBS3 ; et tout se passe pour les terminaux GSM : GT1, GT2, GT3, comme s'ils communiquaient avec une station de base GSM d'un réseau public GSM.Everything happens, for the PABX switch, as if it were processing DECT terminals via a DECT base station, such as DBS1, DBS2, DBS3; and everything happens for GSM terminals: GT1, GT2, GT3, as if they were communicating with a GSM base station of a GSM public network.

La figure 2 représente le schéma synoptique de l'exemple de réalisation E1 du dispositif selon l'invention. Cet exemple de réalisation comporte :

  • une interface radio DR conforme à la norme DECT,
  • un dispositif DE relié à cette interface radio DR et imitant n terminaux DECT, n étant le nombre maximal de terminaux GSM devant être desservis par le dispositif E1 ;
  • une station de base GSM, BTS, constituant une interface radio GSM ayant la capacité nécessaire pour communiquer avec n terminaux GSM ;
  • un contrôleur de station de base GSM, BSC, relié à la station de base BTS ;
  • et un dispositif de conversion, C, couplant le dispositif DE et le contrôleur de stations de base BSC.
FIG. 2 represents the block diagram of the exemplary embodiment E1 of the device according to the invention. This exemplary embodiment comprises:
  • a DR radio interface conforming to the DECT standard,
  • a device DE connected to this radio interface DR and imitating n DECT terminals, n being the maximum number of GSM terminals to be served by the device E1;
  • a GSM base station, BTS, constituting a GSM radio interface having the capacity necessary to communicate with n GSM terminals;
  • a GSM base station controller, BSC, connected to the base station BTS;
  • and a conversion device, C, coupling the DE device and the base station controller BSC.

Le dispositif de conversion C réalise les fonctions suivantes :

  • procédure de déclaration pour n terminaux GSM, le dispositif C et le dispositif DE se comportant comme n terminaux DECT vis à vis de la station de base DBS1 ;
  • transcodage du code de parole GSM (16 Kb/s) en un code de parole qui est accepté par le commutateur privé PABX (64 Kb/s), et inversement ;
  • conversion du protocole de signalisation CM normalisé par le GSM, en protocole de signalisation DECT/GAP qui est accepté par le commutateur privé PABX, et inversement ;
  • et déclaration des terminaux GSM des visiteurs.
The conversion device C performs the following functions:
  • declaration procedure for n GSM terminals, the device C and the device DE behaving as n DECT terminals with respect to the base station DBS1;
  • transcoding of the GSM speech code (16 Kb / s) into a speech code which is accepted by the private switch PABX (64 Kb / s), and vice versa;
  • conversion of the GSM standardized CM signaling protocol to the DECT / GAP signaling protocol that is accepted by the PABX private switch, and vice versa;
  • and declaration of the GSM terminals of the visitors.

Pendant la procédure de localisation, le dispositif de conversion C ne mémorise rien, il retransmet la requête du terminal au commutateur PABX.During the localization procedure, the conversion device C memorizes nothing, it retransmits the request of the terminal to the PABX switch.

Optionnellement, le dispositif C permet de crypter les communications entre les terminaux GSM : GT1,GT2, GT3, etc, et le dispositif E1, sans disposer de l'algorithme secret de cryptage de chaque terminal. Au préalable, une opération manuelle consiste à fournir à la carte SIM (Subscriber Identity Module) du terminal GSM un nombre aléatoire et une clé secrète au terminal, pour lui faire calculer, par son algorithme secret, un résultat fonction de ce nombre aléatoire et de cette clé. Le dispositif C mémorise, pour chaque identité IMSI de terminal GSM, le nombre aléatoire, la clé secrète, et le résultat. Pour lancer le cryptage d'une communication, le dispositif C envoie au terminal cette clé secrète et ce nombre aléatoire.Optionally, the device C makes it possible to encrypt the communications between the GSM terminals: GT1, GT2, GT3, etc., and the device E1, without having the secret encryption algorithm of each terminal. Beforehand, a manual operation consists in providing the SIM card (Subscriber Identity Module) of the GSM terminal with a random number and a secret key to the terminal, in order for it to calculate, by its secret algorithm, a result function of this random number and of this key. The device C stores, for each GSM terminal IMSI identity, the random number, the secret key, and the result. To start the encryption of a communication, the device C sends the terminal this secret key and this random number.

Le dispositif E2 ne diffère du dispositif E1 que par le fait qu'il ne comporte pas d'interface radio DR conforme à la norme DECT. Il échange des trames DECT avec le commutateur PABX, directement sur la liaison filaire L.The device E2 differs from the device E1 only in that it does not comprise a DR radio interface according to the DECT standard. It exchanges DECT frames with the PABX switch, directly on the wired link L.
